OpenStudy (anonymous):

That looks correct to me but I could be wrong. I'm not sure. >.<

OpenStudy (anonymous):

first off, if it rose one and a quarter inches if four and a half hours, it certainly didn't rise over 3 inches in one hour did it?

OpenStudy (x__hazel__x):

Correct!

OpenStudy (anonymous):

they are asking you to do this \[\large 1\tfrac{1}{4}\div 4\tfrac{1}{2}\]

OpenStudy (x__hazel__x):

Thats what I thought! XD

OpenStudy (anonymous):

first turn them in to improper fractions

OpenStudy (x__hazel__x):

Okay! \[1 \times 4 = 4 + 1 = \frac{ 5 }{ 4 }\] \[4 \times 2 = 8 + 1 = \frac{ 9 }{ 4 }\]

OpenStudy (x__hazel__x):

So, \[\frac{ 5 }{ 4 } \div \frac{ 9 }{ 4 } = 0.27777777777\]

OpenStudy (anonymous):

mistake on the second one, the denominator is 2 for that one

OpenStudy (x__hazel__x):

Ohhh, sorry! XD

OpenStudy (anonymous):

so we are at \[\frac{5}{4}\div\frac{9}{2}\] right ?

OpenStudy (x__hazel__x):

\[\frac{ 5 }{ 4 } \div \frac{ 9 }{ 2 } = 0.27777777777\]

OpenStudy (x__hazel__x):

yes!

OpenStudy (anonymous):

do you see any decimals in your answer choices?

OpenStudy (x__hazel__x):

No, we have to convert it :3

OpenStudy (anonymous):

no you don't just don't use decimals none of your questions involve decimals

OpenStudy (anonymous):

first we have to know how to divide by a fraction flip the second one and multiply so \[\frac{5}{4}\div \frac{9}{2}=\frac{5}{4}\times \frac{2}{9}\]

OpenStudy (anonymous):

cancel first, multiply last

OpenStudy (x__hazel__x):

Okay!

OpenStudy (anonymous):

what does you get?

OpenStudy (x__hazel__x):

I got the same thing O.O

OpenStudy (anonymous):

i mean as a "final answer" ?
